There was a time when second base was a wasteland in the minors, when utility types like Taylor Green topped the prospect rankings just because they were the only ones with a chance of contributing in the not-too-distant future.

And after a year in which Jedd Gyorko, Anthony Rendon, Jurickson Profar and Scooter Gennett all graduated to the majors, you'd think that time would be now.

But times, they're a-changin'. Failed shortstops and relocated outfielders have given the position considerable depth, and the last generation has left this one with considerable opportunity. Of the 10 second base prospects listed here, four might actually be worth drafting in standard mixed leagues. That's unprecedented.

Of course, for what second base offers in depth, it's lacking in upside. None of these players profiles as a future first-rounder. Still, in dynasty leagues, you shouldn't have to extend yourself to get something useful for the long haul.

Note: This list has been adjusted for Fantasy purposes. Though long-term potential is a factor, it's arguably less important than the player's expected role in 2014. These prospects don't all profile as superstars, but they're the names most worth knowing in Fantasy right now.

Taken 22nd overall in the 2011 draft, Kolten Wong's ascension to the majors in mid-August may have seemed abrupt to some, but based on the .303 batting average he put together at Triple-A, he didn't have much more to learn in the minors. Of course, given the numbers he had in the majors, you might wish he did, but keep in mind he was splitting time with David Freese, with Matt Carpenter shifting from second to third base as necessary, and may have gotten worn down playing deeper into the year than he was accustomed to doing. A high batting average is probably the one certainty for the 5-foot-9 Hawaii native, who has so far made the most of his his minimal tools, generating more power than expected for a player his size and making judicious use of his moderate foot speed. He has all the makings of another Jose Altuve, but perhaps with a little more power and a little less speed. Of course, for Fantasy owners to get anything out of it, he has to have a place to play, but if the Cardinals find a taker for David Freese this offseason, Wong will be a sleeper in all formats. He's already a must-draft in NL-only leagues.

2. Alexander Guerrero, 27, DodgersWhere played in 2013: Did not play -- in Cuba

Looking to upgrade at second base in a way that wouldn't require them to drop $300 million on Robinson Cano, the Dodgers rolled the dice on Cuban defector Alexander Guerrero in late October, signing him to a four-year, $28 million deal. Of course, that contract probably says more about their deep pockets than their confidence in the 26-year-old. As with most Cuban defectors, the scouting reports on Guerrero are lacking in detail and subject to hunches. In a league that many talent evaluators compare to high Class A, his numbers were adequate, but not eye-popping. Agent Scott Boras has compared his power to Dan Uggla's, which may or may not be an exaggeration, but as critical as scouts have been of Guerrero's swing-at-anything approach, the similarities to Uggla may not end there. Guerrero will get every chance to win the starting job out of spring training and will probably perform well enough to justify a late-round pick in mixed leagues. Just be careful not to lump him in with fellow Cuban defector Jose Dariel Abreu. Even in a best-case scenario, the outlook isn't as rosy.

Rougned Odor's name may be a familiar one to prospect hounds -- partially because once you see it, you don't forget it -- but 2013 was the first year the results began to live up to the projections. As one of just three teenage position players in the Carolina League, Odor piled on the doubles and showcased better-than-expected base-stealing ability. Then, after a promotion to Double-A Frisco, he more than doubled his home run total in only 30 games. His numbers aren't off the charts, but for how far he has climbed at such a young age, they're awfully encouraging. His well-rounded production is similar to what Jurickson Profar delivered in his abbreviated minor-league career, though Odor's stock hasn't quite reached that level yet. In terms of pure upside, he's probably the best second base prospect in baseball right now, but with the Rangers overloaded up the middle already, he's a long shot to reach the majors as more than a September call-up. Dynasty league owners should begin taking him seriously as a long-term keeper, though.

Jonathan Schoop is one of those prospects who make Fantasy owners thankful for all the work scouts do. A regular schmo just looking at the minor-league numbers might not give him the time of day, but here he is on the verge of stepping in for Brian Roberts at second base. He got a quick audition for the role late last September and didn't do anything to jeopardize his chances, but his less-than-stellar minor-league numbers might give the Orioles reason for pause. Still, scouts have always liked his power, and he delivered more of it last year than first glance would have you believe. All nine of his home runs at Triple-A came on the road, which suggests he was a victim of Norfolk's spacious ballpark. He also dealt with his share of injuries, as has been the norm throughout his minor-league career. Schoop probably won't get the buzz of a Kolten Wong or Alexander Guerrero on Draft Day, but particularly if he has a starting job to himself coming out of spring training, he's a good bet to factor in mixed leagues before season's end.

Tommy La Stella wasn't on anybody's radar until Dan Uggla's impromptu laser eye surgery in mid-August sent everyone scrambling to the minor-league leaderboards to figure out who would take his place. And what they found at Double-A Mississippi gave them little reason to keep searching. The Braves didn't turn to La Stella then, but judging by the rumors of them looking to unload Uggla this offseason, they'll likely give him a shot this spring, especially with his OPS rivaling that of mega prospect Kris Bryant in the Arizona Fall League. A lot of that is on-base percentage -- La Stella's power isn't even in the same ballpark as Bryant's -- but it demonstrates just how thoroughly he excels in that facet of the game. Not only does he make consistent, hard contact, hitting .327 over three minor-league seasons (and none of them in especially hitter-friendly environments, mind you), but he's a walk machine. Granted, that skill set will only carry him so far in Fantasy, but seeing how Matt Carpenter has fared without big-time power or base-stealing ability, you wouldn't want to overlook La Stella, particularly in NL-only leagues.

A non-entity in the Red Sox farm system in 2011 and 2012, Betts burst onto the scene as a 20-year-old getting his first taste of full-season ball in 2013, only improving after a midseason promotion to high Class A Salem. There, he hit .341 with seven homers, 20 steals and a .966 OPS in 185 at-bats, solidifying his breakthrough. He didn't improve in just one area. His batting average, home runs and stolen bases all increased, and with 81 walks to 57 strikeouts, his plate discipline was as good as it gets for a minor-leaguer. The performance was so out of left field that you have to guard against the possibility of a letdown, particularly as he makes his biggest jump yet to Double-A Portland. But if it was even halfway legitimate, Betts has a future in Fantasy. He's a must-have now in dynasty leagues because of that possibility, though with Dustin Pedroia locked up long-term, he's at least a couple years from reaching the majors.

After swiping 101 bags about as quietly as a player can in 2012, Delino DeShields regressed to "only" 51 in 2013. OK, so he's not Billy Hamilton, but he still projects to steal a bunch of bases in the majors. And judging by his jump in batting average with his move to high Class A, he projects to do more than just that. The problem for DeShields is he may no longer be eligible at second base by the time he gets the call. He hasn't taken to the position defensively, and the Astros just locked up Jose Altuve long-term. A move to the outfield in the Arizona Fall League offers a glimpse into DeShields' future. Granted, an elite base-stealer is still plenty valuable in the outfield, but second base is still considered the weaker position. At age 21, DeShields remains a work in progress, so you shouldn't expect to see him this year. If his pedigree as the eighth overall pick in the 2010 draft allows him to develop power in the years ahead, he'll be quite the prize in long-term keeper leagues.

The Twins transitioned Eddie Rosario from center field to second base in 2012 in part because they felt they had a need there long-term. But with Brian Dozier's emergence in 2013, the Twins can afford to take it slow with the 22-year-old. In long-term keeper leagues, it's probably for the best. Rosario held his own after a midseason promotion to Double-A New Britain but still hasn't demonstrated the full extent of potential. He won't ever rank among the league leaders in home runs or stolen bases, but he'll contribute a fair number of both -- and with a high batting average to boot. Comparing him to Martin Prado might seem to be shortchanging his upside in some ways, but if that's the kind of player he ends up being, he'll have been well worth the investment. Just don't count on him getting more than a September call-up in 2014.
